Summary Introduction

To analyze:

The collenchyma cells involve in providing support to the plant tissue.

Introduction :

Along with cell wall in plant cell there are many different cells that have specific function and form tissues. There are three types of cells that form the plant tissues. They function together to provide food production and storage, give flexibility, support, and strength to the plants. Parenchyma is the most flexible and thin cell found in the plants. They are responsible for the structure of plants and have many other functions like food storage, gas exchange, photosynthesis, and protection. The next cell is collenchyma; they are cylindrical in shape and give support around the cell. They consist of unevenly thickened cell walls. This cell retains the ability to process cell division once they get matured. The third cell is the sclerenchyma; they lack cytoplasm and other living components once they get matured. They have thick and rigid cell wall; they are involved in providing support to the cell and also help in transportation of materials within the cell.

Explanation of Solution

Collenchyma is ground cells are cylindrical in shape and give support around the cell. They consist of unevenly thickened cell walls. This cell retains the ability to process cell division oncethey get matured. Their cell wall is made of cellulose deposit because of which a thick layer is formed with longitudinal interlocking, this help them to support the surrounding cells.

Conclusion

Collenchyma have unevenly thickened cell walls that help them to support the surrounding cells.
